PROCESS OF DESICCATING SLOP.

Application filed July 31, 1911. Serial No. 641,543. 1

Be it known that I, CHARLES E. GEIGER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Processes of Desiccating Slop, of which the following is aspecification.

This invention relates to a process for recovering valuable roducts' from slop, suchv as that obtained om distilleries and 'the like, and one of the principal objects of the invention is to provide a process in which.

slopof diflerent consistencies may be successfully treated.

For the attainment of these ends and the sists in the process and the apparatus for efiecting the operation of the process substantially as hereinafter described.

In: the accompanying drawing Flgure 1 :is a view in elevation of an apparatus for effecting the carry ng out of my process, and

Fig. 2 is a plan view of the same,

It is found in treating; mixtures containing spent grains and liquid such as 1s found in distillery slop and the like, that the mix- 1 tureobtained om the difierent grains is not always of the same consistency. That is, in desiccatin the more solid materlals from a semi-soli mixture it is necessary to vary the process "for mixtures in which the solid materials are of different proportions.

'Another diflicultyencounteredin drying the more solid materials is that in mixing a syrupwith thez'materials as they are fed into a dnenthe syrup causes the material to to'rm in a gum like mass;

The present invention is designedto obviate these difliculties, and to present a process in whichslopof-varied consistencies may be treated by :the same desiccatin'g apparat'us.

In the b I slop is first ted into'a separator, which may be, and preferably is, of an inclined type, and imwhichthemore solid materials are caught by a" screen, allowing the liquid to filter'through the screen.- The more solid material is then allowed to fall by gravity,

or is discharged-upon enflesshelt or com process nowto'be described the veyer which carries the said material under Patented Mar. 25, 19 13.

a press wherein more of the liquid contained in the? solid material is pressed therefrom and the material is discharged into a drier. The liquid first obtained from the separator is collected and discharged by suitable means into an evaporator by which the liquid is made into a syrup. The 'li l id obtained from the press is discharge at the to of the first named separator, where it is re ltered.

A receptacle is rovided which contains a filler which may he ofany desired or suitable material, such as meal or chopped feed, which may also be discharged into the drier. After the material issues from the drier it is conveyed to a mixer where it is mixed with syrup from the evaporator and the mixture thusformed is then discharged into another di'ier or driers, from which it is discharged in a form ready to be used.

It is evident that by using this process slop of any consistency may be desiccated, and that there is no danger of the more solid materials becoming gummed or sticking in the drier.- Furthermore, if the materials about to be discharged into the drier at first are too thin or contain too much moisture,

they may be mixed with a filling material which will give the mixture the necessary or required body. To effect the operation of n this process I have shown and will now describe the preferred construction, combination and arrangement of an apparatus for carrying out the above-described process.

7 In the accompanying drawing the slop is discharged from a pipell into an inclinedv separator 12, which is formed with a screen '13 and is adapted to permit the liquid part and to'be carried down the bottom of the of the mixture to filterthrough the screen separator, from whence it is pumpedby a pumplli into an evaporator 15. The more solid materials slide down the screen 13 by gravity or are conveyed from the separator to a moving belt or conveycr 16. This con veyer 16 passes through the pressing: rolls .17 in' such a manner that the liquid contained in the materials as they are dis charged from the separator 12 is further removed and caught in a receptacle '18. Freinthe' conveys? 16- the dried materials by the syrup may be mixed the material finally being I separated in .the

then pass into the hopper 19 of a drier 20. The liquid caught inthereceptacle 18 is returned by means of a pump 21 to the top of the separator 12, where the liquid is again filtered with the slop as it comes from the discharge pipe .11. Connected with the evaporator 15 is a distributing pump 22, with distributing'mains 23, for discharging the syrup formed inthe evaporator.

Suitablylocated adjacent the drier, 20 is a filler receptacle 24, which is adapted to contain meal or cut feed for supplying body to the materials to be dried in the drier. A conveyer 25' arranged beneath the receptacle 24 is adapted to discharge material therefrom into the hopper 19 of the drier, the syrup distributing mains having an outlet into the mixing conveyer 25, wherewith material from the'filler receptacle 24.

After the mixture emerges from the first drier 20 it is conveyed by means of the conveyers 26 and 27 to one of the conve ers 28. hese conveyers 28 are provided with outlets from the syrupv distributing mains 23, and are adapted to mix the materials delivered to them with the syrup and to dis charge the mixture thus formed into one of thedriers 29. This drying operation may be continued to any "degree of refinement, discharged from the drier into a conveyer 30.- I From this description it is evident that the more solid material may be recovered from the slop simply by separating the,

liquid portions from the more solid portions and by drying the latter in the drier; or the more solid materials may be mixed with the liquid which is re-filtered with the incoming slop thus obtained dried; or the more solid materials may be mixed with a syrup after the first drying process; or the more solid materialscmay be mixed with the filler in the first drier, the filler being formed with or without the syrupl It is evident that thesetvariations may all be made together with many others, without varying the construction or operation of the several parts, andit is further evident that others skilled in the arts .to which this process and apparatus relate may make various changes without departing from the spirit and scopeof my invention.

What I claim as new is: e

'1. The process of desiccating distillery slop, which consists in separating the more solid portions from the liquid; in evaporating the liquid obtained to a syrup; in pressing the solid matter to remove more of the liquid; in' returnin this liquid to. be remeans; and in drying the more solid ma- 'terials.

2. Theprocess of desiccating distillery and the more solid portions rst named separatingtherefrom to a syrup;.in pressing the more solid portions to remove more of the liquid; in returning the liquid thus obtained to the first named separator; in drying the more solid portions; in mixing the syrup with the dried solid portions and in further drying the said mixture.

3. The process of desiccating distillery slop which consists in filtering the more solid portions from the slop; in pressing the said solids to remove more of the liquid; in evaporating the liquid firstcbtained to a syrup; in returning the liquid pressed out to the first named separator; in dryin the solids; in mixing the syrup with the ried solids; and in further drying, mixing and drying the said mixture.
